  2. Flow mark - Wikipedia

    en.wikipedia.org/wiki/Flow_mark

    Increasing the temperature of the material or mold allows the material to flow without stiffening before the cycle completes. [ 1 ] If the temperature is increased too high, there is a chance to cause a different type of injection molding defect referred to as a burn mark .

  3. Injection moulding - Wikipedia

    en.wikipedia.org/wiki/Injection_moulding

    Injection moulding (U.S. spelling: injection molding) is a manufacturing process for producing parts by injecting molten material into a mould, or mold. Injection moulding can be performed with a host of materials mainly including metals (for which the process is called die-casting ), glasses , elastomers , confections , and most commonly ...

  4. Design of plastic components - Wikipedia

    en.wikipedia.org/wiki/Design_of_plastic_components

    The design of injection moulded components can be further improved and optimised by using injection moulding simulation software such as Autodesk Moldflow [5] and SolidWorks Plastics. [6] This software works with components designed in CAD to simulate how a polymer behaves when it enters a injection mould cavity.

  5. Weld line - Wikipedia

    en.wikipedia.org/wiki/Weld_line

    In manufacturing, the Weld line or Knit line or Meld line is the line where two flow fronts meet when there is the inability of two or more flow fronts to "knit" together, or "weld", during the molding process. These lines usually occur around holes or obstructions and cause locally weak areas in the molded part. [1]

  6. Fusible core injection molding - Wikipedia

    en.wikipedia.org/wiki/Fusible_core_injection_molding

    Traditional horizontal injection molding machines have been used since the mid-1980s, however loading and unloading 100 to 200 lb (45 to 91 kg) cores are difficult so two robots are required. Moreover, the cycle time is quite long, approximately 28 seconds. These problem are overcome by using rotary or shuttle action injection molding machines.

  7. Injection mold construction - Wikipedia

    en.wikipedia.org/wiki/Injection_mold_construction

    Injection mold construction is the process of creating molds that are used to perform injection molding operations using an injection molding machine. These are generally used to produce plastic parts using a core and a cavity. Molds are designed as two-plate or three-plate molds, depending on the type of component to be manufactured.

  9. Gas-assisted injection molding - Wikipedia

    en.wikipedia.org/wiki/Gas-assisted_injection_molding

    The basic concept of the gas-assisted molding process is quite similar to the regular injection molding process. In gas-assisted molding, the plastic material is injected into the mold cavities like the regular injection molding process but only up to 70%~80% of the mold volume. The melted plastic in contact with the mold walls begins to ...
